.To ZZ whom t may concern:

Be it known that I,`SIL'As C. RAND, a citi/:en of Great Britain, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in. 'liic-Casings, of which the following is a specification.

'lhis invention relates to improvements in tire casing-s.

.l'he main objects of my invention are: First, to provide an improved tire casing in which the tire is supported by' a fabric well adapted to sustain the various stresses 'towhih it is subjected in use.

meut of my invention is clearly illustrated yimproved tire:

in the accompanying drawing, forming a part of this specificatiomin which:

Figure I is a cross section of a tire embodying the features of my invention, the same being shown upon a rim, the rim being shown conventionally. A Iiig. II is a detail plan view of a section of rope from which I form the fabric'of my Figi. III isa cross section .on spondingffto -line 3; 3 o'fFig. II.

In the drawing, similari reference characters refer to similar parts' throughout the several views.

Referring' to the drawing, the' rim 1 is shown conventionally and is illustrated merely to show an application` of my ima line corre-j pro vcmonts.

The fabric or casing body 2 of my improved tire casing is formed of strands loosely braided into a rope as illustrated in Figs. II and III, preferably as an endless or annular part and then compressed or conformed into a U cross section or into a cross section corresponding to that of the casing.

The strands are braided quite loosely so that'the rope may be compressed and conformed into U shape, and when so compressed and shaped the fabric is formed of strands interbraided and interlocking in every direction and extending longitudinally and transversely across the tire.

I preferably interweave bead strands 3 with the edge strands of the fabric.

The conformed braided strands are embedded in rubber 4 so that the spaces or. interstices between the strands are filled with the rubber and the inner and outer faces 5 and G respectively are provided for the fabric. The inner and outer faeings are interloclred with each other throughout the casing' by the portions between the strands. The strands are so interbraided and interlocked that while they support the strains and stresses in every direction they permitA great freedom of movement.

The tire is Very resilient and may be sub- .jecte'd to a great deal of flexing movement without serious injury 'to the fabric.

I preferably provide an outer tread or wear portion 7 of different composition from that embedding and facing the fabric.

I illustrate an inner tube 8 which is disposed within the casing` in the usual manner, the inner side of the tube being protected by the strip 9'.

My improved tire is, as stated, economical t 'produce and at the Sametime has great strength and durability `and maybe used under less pressure than tires as commoniyIV f constructed without serious 'in-jury thereto.

Havinqthus described my invention, what I claim a new andl dsire to secure by Letters Patent, is?" y"1. A tire easing consisting of a single annular fabric, l the strands of which are braided as in a rope, a resilient compound fillingbetween and embedding the strands and forming an inner and outer casing for the fabric, and a resilient tread portion secured to the outer casing portion of such embedding compound:
